Multifunctional differential pressure transmitters with air flow measurement and Modbus communication

DPT-MOD is a multifunctional transmitter for measuring volume flow, velocity, and static and differential pressure. The measurements can be read and the configuration done via Modbus communication. DPT-MOD requires less wiring than the traditional 3-wire transmitters because multiple devices can be connected on serial line. DPT-MOD can also be used with several different measurement probes such as FloXact™ or pitot tube, and air dampers.

DPT-MOD series devices include: • Two selectable functions: o Measure and monitor in-duct volume flow, velocity or differential pressure o Measure and monitor air flow across centrifugal fans • Multiple selectable measurement units: o Volume flow: m³/s, m³/h, cfm, l/s o Velocity: m/s, ft/min o Pressure: Pa, inWC, mmWC, kPa, mbar • Modbus communication protocol

DPT-MOD series device options offer: • AZ (autozero) function for automatic zero point calibration, eliminating the need for periodic manual autozeroing to ensure long term accuracy
